6 Claims.

The present invention relates to 'p'yrophoric lighters for use with aliquifled gas, and more particularly to pocket cigar lighters.

It is an object of the present invention to provide a pyrophoric lighterwith a detachable gas tank which can be easily removed and exchanged.

It is another object of the present invention to provide a pyrophoriclighter in which the parts are locked when in operative position.

The invention comprises a detachable gas tank; a device mounted on saidtank for releasing and igniting the gas; a sheath partially enclosingsaid tank; means mounted on said sheath for controlling saidgas-releasing device; a casing arranged to envelop said sheath enclosingsaid tank and carrying said controlling means; and a detachabledint-holding device engaging said sheath and engaging said casing andforming a locking means for holding said sheath and said casing inposition.

The novel features which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with additional objects and advantages thereof, willbe best understood from the following description of specic embodimentswhen read in connection with the accompanying drawings, in which:

Figure 1 is a vertical section of the lighter according to theinvention.

Figure 2 is an end view of the lighter.

Figure 3 is a vertical section along line A-B of Figure l. Y

Figure 4 is an horizontal section of the lighter along line C-D ofFigure 1.

Figure 5 is a vertical section along line E-F, of Figure 3.

Figure 6 is an horizontal section along line G--H of Figure 5.

As can be seen from these drawings, the cigar lighter comprises a caseor outer envelope I, closed at its base by a removable bottom la (Fig.2). Inside this case is housed the tank 2, comprising a closed envelopecontaining the liqueed compressed gas used as a fuel. On an inclinedpart of the roof of the tank 2, the gas releasing device 3 is arranged,through which the expanded gas escapes, and which, in the shownembodiment, also acts as a burner, the assembly of the tank and the gasreleasing device forming a unit.

The tank unit 2, previous to its insertion in case I is engaged inside asheath 4 which partially surrounds it and which, on its side edge, has anotch 4 allowing the easy disengagement of the tank unit.

A removable sheath 5 is provided between the movable bottom -I of thecase and the sheath 4 containing the tank unit 2 in order to hold thesheath and the tank unit in position.

In the upper part of case I, above the sheath 4 of the tank, is arrangeda small independent casing 6, wherein is housed the whole of the controlmechanism for the gas releasing and igniting device 3. This mechanismcomprises a small plate I bearing on the lower bottom of the casing 6and including two ears 'Ia which serve as bearings for an axle 8 onwhich a lever 9 is mounted for rotation whose end terminates into a fork9a arranged under the head of the releasing and igniting device 3(Figure l). A spring I0, for instance a torsion spring, tends to pulldownwards the end of the fork 9a of lever 9. On axle 8 are articulatedthe two downwards moving ears I Ia of a small plate I I, which pressesagainst the upper part of case I and which is extended yby a lever I2whereon is attached a push control I3 extending outwardly through anaperture Ib of the case. In the upper part of the case, next to thecasing G, is housed a second small casing I4 (see Figures 3, 5 and 6),wherein is engaged the stem I5 of the flint holding device, extended byyoke I6, whose axle carries the ignition wheel I'I for acting on theferrocerium flint IB and its control wheel I8. A lining I!)8L closes, atits base, the casing I4, so as to leave in the latter an aperture of aparticular shape which allows the replacing of the flint holding devicein a correct position in its housing.

An aperture Ic, provided in the upper part of the case (Figures 1 and 2)above the burner 3'* of the gas releasing device 3, allows the exit ofthe flame from said burner.

The two small upper casings 6 and I4 are formed by an S-shaped platewhich is attached to the upper part of sheath 4, so as to allow theirremoval from the case, together with the sheath and tank. Once thesheath is in position inside the case, the flint holding device engagedin casing I4 constitutes a lock which prevents any undue exit of thesheath together with the tank and the control mechanism for the gasreleasing device.

The operation of the cigar lighter so designed is effected very simplyby depressing the push control I3, which, through the action of theforked lever 9-9, causes the opening of the gas releasing device 3, and,consequently, the

exit of the gas. By acting at the same time on The replacement of theferro-cerium int, after it has been worn out, is effected very simply bywithdrawing the iiint holding device from casing Il. 'Ihe replacement ofthe gas tank 2 is effected by removing the lower bottom I'I of. case land by withdrawing the sheath 4 together with the tank 2 which itpartially clamps, after having, ofcourse, previously withdrawn the ilintholding device to unlock the sheath. 'I'he tank is easily removed fromthe sheath by pushing it through the side notch l* o the latter.

The tank used with this cigar lighter is preferably a tank containing aninner absorbent support for producing a rst expansion of the gas of thekind described in our copending U. S. application No. 757,314 iiled onJune 26, 1947. The releasing device carried by this tank is preferablyof the type described in our copending application U. S. No. 646,540,filed on February 9, 1946.
